I have an older Trane furnace. I have had HVAC people out here, but they are not listening to me when I describe what it does, so I was hoping to get some public input on this issue.
The house will heat up to 70, the heat goes out (as it should), but the blower keeps going. No, this is not just a few minutes. If you leave it, the blower continues to run, and the heat never kicks back on. The only way to get it to stop is to turn off the power to the furnace.
The thermostat's fan is is set on "auto" not "on".
We changed the thermostat thinking that was the issue, but that didn't fix it.
